Same. I just moved my 77 year old mother to Mint (LMDE). It went very smoothly. The only complaint has been that Thunderbird does not suggest addresses from people that have emailed her in the past when she is sending a new message. This is just because it is a fresh install. It will learn these over time.

I used the Windows 10 end-of-support as an excuse. The real value though will be to get off the treadmill that made her create a Microsoft account and pin that she did not want and that will certainly subject her to a bunch of advertising and AI in the future.
